Great App!

This app has been perfect for my at-home workouts. My only suggestion is for them to allow you to reset the number of total intervals you have done p/workout. For instance, I currently am doing a HIIT workout that includes 5 moves, done for 45 seconds on with 30 seconds rest between. When I finish, it’s telling me my accumulated intervals from the very first workout I ever did with the app, rather than just the 5 rounds I’m trying to keep track of this one day. An additional option of adding how many rounds p/workout would be dope!

Great App for Tracking Intervald

This app allows for the setting of a workout time and a break while giving the ability to continue to cycle. Which is much better than resetting 20 second timers. Though I think the app should all the beeping sounds during the workout period and break period to alert the user of the shift, because some excercises go back to back. This feature would making tracking your position in the workout even better.

Very good, a few flaws

I purchased this app to support my home physical therapy program. From my PT point of view, there are 2 flaws: #1. Many PT exercises require less than the current minimum of 5 seconds of " work" and "rest". For example, supine hip abductions require me to hold for 2 seconds (work), then 1 second of rest, repeating 30 times. So, it would be helpful to include 0:01, 0:02, 0:03; and 0:04 in the Work and Rest sliders. #2. The app could be more helpful if users like me could "drag and drop" to change the order that the workouts are displayed, to coincide with the order the exercises should be performed. #. With these enhancements, my rating would be 5 stars.

Developer Response ,

Thanks for the suggestions, they're great! We'll enhance the app to support order change and 1s incremental.
